This event was captured on a home security camera on march 11, 2017 @ 2:20 am in palm springs california. it started outdoors inside an 8 foot walled courtyard. flew through a closed sliding glass door (without breaking the glass). then, circled around the indoor kitchen before flying out of sight of the camera view range. it moves extremely fast and appears to flutter and could have wings. i am attaching the canary camera video clip as well as some still shots taken from the video.
